摘要： PROBLEM TO BE SOLVED: To eliminate the problem including troubles that particles themselves flocculate with air entrained in powder flocs, unreacted regions with water or incompletely mixed regions arise, coal ash as a principal raw material has poor wettability by water, etc., which result in insufficient hydration bonds after being formed and cured and therefore the low strength of plates because a conventional method for producing coal ash plates by using cement as a binder has not specified a kneading condition before forming or quantities of water and the like. SOLUTION: Compact and high-strength coal ash plates are formed by blending powder particles where cement as a binder is added to coal ash with the necessity minimum added of water, followed by carrying out operations of kneading them and mixing them together under a pressurized condition to perform pressure forming by means of a mold or die and then by curing. Consequently, the usage rate of added coal ash is profitably high and a special additive is economically needless, and compactness and high strength can be secured due to a contribution to cohesion between powder particles by the hydration bonds of cement particles and the pozzolanic reaction of coal ash particles.

摘要： PROBLEM TO BE SOLVED: To obtain coal ash-based artificial aggregate having resolved such problems that, in the method for producing artificial aggregate by a conventional wet kneading technique, coal ash and cement are sprinkled with water prior to granulation, but kneading conditions or the quantities of water, etc., are not specified; therefore, the particles themselves are set with air entrained into the powder lumps, unreacted-with-water region or incompletely mixed region is formed, and coal ash as the main feedstock is poor in wettability with water, leading to insufficient hydration bond formation after granulating and curing the feedstock mixture, and resulting in low mechanical strength of the final artificial aggregate. SOLUTION: The coal ash-based artificial aggregate is obtained by the following process: coal ash is incorporated with cement as binder, the resultant powdery particles are then admixed with the necessary minimum quantity of water followed by kneading the mixture under high pressures and then granulating it, the resultant granules are cured. Thus, availability of the coal ash incorporated is high, therefore being beneficial, and because of no need of any special additive, the above process is economical; besides, since the hydration bond formation of the cement particles and the pozzolanic reaction of the coal ash particles contribute to the bond formation among the powdery particles, the coal ash-based artificial aggregate obtained above can secure its high density and high mechanical strength.

摘要： PROBLEM TO BE SOLVED: To provide an oxidation or decomposition method allowing a gaseous organic substance to be efficiently in contact with a catalyst, using titanium oxide having a large surface area, which solves problems wherein titanium oxide formed by pelletizing fine powder is used as the catalyst and is formed spherical so as to prevent crushing of the pelletized catalyst, such molded bodies have superior strength, however have less surface area per unit weight and inferior efficiency, and therefore a large amount of them has to be packed resulting in high pressure loss in a catalyst layer. SOLUTION: In this oxidation or decomposition method, titanium oxide is heated to be activated, and organic matter and reactive inorganic matter are oxidized or decomposed by the heated catalytic function in a heated state. The catalyst is formed into a shape with a large surface area by press-hardening fine powder into irregular forms, is obtained by using titanium oxide with a bulk specific gravity of 1.2-3.2, a size of 1-60 mm and a specific area of 2.0 times or more of that of the spherical titanium oxide of the same specific gravity and weight.
